HARVESTER-BINDER.

SPECIFICATION forming part of Letters Patent No. 708,320, dated September 2, 1902. Application filed OctoberlO, 1900. Renewed July 30. 1902. Serial No. 117.710. (No model.)

T0 all r11/"7,0m t may concern:

Be it known that I, JOHN ALEXANDER OOWAN, agent, of the city of Calgary, North` West Territories, Canada, have invented certain new and useful Improvements in Harvester-Binders, of which the following is a specification.

The object of my invention is to devise a harvester-binder in which the grain is ele vated to a minimum height during the process of forming and binding the sheaves, pertaining more especially to that class Vof harvester-binders having an open rim or ground- Wheel having a truck running ona track formed on its inner periphery and a harvester-frame pivoted at one end of the truck and vertically adjustable upon its other end.

It consists of the novel combinations, arrangement, and adaptation of parts, as more fully hereinafter described and claimed.

Figure lis an end elevation of my improved harvester-binder. Fig. 2 is a front'sectional elevation of the same through the line a: y, Fig. l. Fig. 3 is a perspective view showing the means for retaining the grain on the elevator side of the binder during the process of binding. Fig. 4 is a perspective detail showing one form of adjustable connection between the rear portions of the harvester frame and truck. Fig. 5 is Aa skeleton view showing the method of adjusting the height of the harvester binder-frame. y

In the drawings like letters of reference indicate corresponding parts in the different figures.

A is the frame of the binder, suitably shaped to support the different parts. B and O are arms extending laterally therefrom. The outer ends of these arms are turned downwardly and havealongitudinal barD secured thereto immediately opposite a similar bar E,

connected to the frame A.

F is a truck comprising the frame G, the main wheel H, and the guide-wheels I. The frame G is so proportioned that the guidewheels I are located on or near an imaginary line forming the diameter of the open rim or ground wheel J. This open rim has a triangular track K formed on its inner periphery, with which the wheels H and I are suitably shaped to engage. Upon the forward end of the frame G at a is journaled the arm l.

The arm O is adjustably connected with the rear of the frame G at Z). One :form of adjustable connection is shown in Fig. 4. A segmental rack L is rigidly connected to the arm O. This rack forms the arc of a circle struck from the center of the journal a and is adapted to slide through a guide-frame M, secured to the frame G. N is a pinion fast on a spindle c, journaled upon the frame G. Upon the one end of this spindle is journaled a lever O, which is provided with a pawl f, adapted to engage the ratchet-wheel d, fast upon the spindle. e is a pawl pivoted upon the frame and also adapted to engage this ratchet-wheel. It is evident that by reciprocating the lever is the pinion N may be caused to elevate the rack L to any desired extent, in which position it is securely held by means of the pawl e. When the rear portions of the frame of the truck and the harvester are so separated and as the tongue of the binder tends to maintain it in a substantially horizontal position, it is evident that the elevation of the binder above the ground may be increased as desired. (See Fig. 5.)

Although the frame may be slightly tilted,

relatively to the ground varies verylittle. It

will be noticed that as the binder is raised the truck assumes an inclined position from the rear forwardly and upwardly.

P is the table of the binder, Q the elevator, and R the binder-deck,which extends through or partially through the open rim J, the apex between the elevator and binder-deck being substantially within the open rim. The elevator is much lower than in an ordinary binder and the binder-deck shorter, thus materially reducing weight and decreasing the amount of handling required during the collection of a sheaf and the binding of the same. The conveyer may be provided with the usual conveying-canvas; but I prefer to use the carrying-chains shown in Fig. 2.

S represents the carrying-chains upon the binder-table, which pass around suitable sprocket-wheels, as shown. Similar chains'I IOO the sprocket-wheelsj upon the shaft g at the upper end of 'the elevator and around the sprocket-wheels h upon the shaft t', upon' which sb aft are also fixed the sprocket-wheels, around which pass the chains S. From a sprocket-wheel 7V on one end of the shaft g extends a sprocket-chain to a sprocket-wheel Z, fast on one end of a shaft U, suitablyjournaled upon the bar D. The other end of this shaft U is provided with a crank-disk fm, from which may be driven the cutter-bar. (Not shown.) Upon the shaft U is fast a bevelpinion n, which meshes with a bevel gearwheel 0, fast upon the cross-shaft p, journaled upon the bars D and E. Upon this shaft is fast a sprocket-wheel q, which is driven by a sprocket-chain from the sprocket-wheel 1', revolving with the main wheel H. From this construction it is evident that the proper motion will be given to the carrying-chains S and T while the machine is in motion.

V is an apron, preferably of sheet metal, supported above the elevator Q, so as to hold the grain in contact therewith. As this apron is fast only at its lower side to the frame s, it accommodates itself readily to the quantity of grain passing up the elevator. To adjust its pressure equally from butt to head of the grain, it is preferably vertically divided, as indicated at t t, so that different portions of it may springindependently of the rest. This apron does not extend to the top of the elevator, but is turned abruptly substantially at right angles toits general direction to form the outwardly-turned upper end u. This end has slots v formed therein, in which play the fingers A', which are connected to the rockshaft B', journaled in the frame s. When these fingers are in the position shown in Fig. 2, they form an extension of the apron V and maintain the grain in contact with the elevator tillitis deposited upon the binder-deck.

As the binder-deck is short and the needle C' passes through it close to the apex, it is necessary to provide means for retaining the grain at the elevator side of the binder during the binding of a sheaf. In order to accomplish this, I provide a series of rods D', which may be extended upwardly through holes at the apex of the binder-deck, as shown in Fig. 3. At the same time that these are extended the rock-shaftBis operated to swing the fingers A' into the position shown in Fig. 3. The grain raised by the elevator is then held between the upper end of the apron V, the fingers A', and the rods D'. To operate the rods D', as described, any suitable means may be provided. In Figs. l and 2 I show a shaft E' journaled upon the frame of the binder and provided with a series of crankarms a', to which the rods D' are pivoted. One end of this shaft is provided with a short crank-arm b', pivotally connected by a suitable connecting-rod with a longer crank-arm c', fast on the end of the rock-shaft B'. The parts are so proportioned that when the shaft E' is rotated to raise the rods D' the fingers A' In order to assist the grain in moving onto.

the lower part of the elevator, I journal a shaft G' within the lower end of the apron V and provide it with a series of disks having fingers d' extending therefrom. These iingers extend through slots in the apron adjacent to the chains S.

The shaft G' is preferably driven by gearing from the shaftz' and at the rear end, as seen in full lines in Fig. l and by dotted lines in Fig. 2. H' is a cover preferably connected to the frame s and extending over the apex of the binder to shield the grain from the iniiuence of Wind.

From the above description it will be seen that I have devised a binder which will operate with a minimum amount of elevation ofthe grain, that I have devised simple means for increasing or decreasing` the height of the binder from the ground, and that I have provided simple and effective means for retaining the grain upon the elevator side of the binder during the process of binding a sheaf.
